よくある質問

Which Markdown flavor?

GitHub-Flavored Markdown (GFM) via marked - tables, fenced code, task lists, autolinks, strikethrough.

Is the HTML sanitized?

Marked emits raw HTML from your input. If you plan to render user-submitted content, sanitize the output with DOMPurify before insertion.

Where is my Markdown sent?

Nowhere. Parsing runs in your browser via a local JavaScript library.
